350 Mission Street

This new, 30-story, 340,000-square-foot tower is located directly across from Salesforce Tower and the Transbay Transit Center development on Mission Street in San Francisco’s rapidly evolving South of Market District.

The $250M project is sited on a tight 19,000-square-foot lot. The tower's design includes 30 stories of Class-A office space, that is 100% pre-leased to salesforce.com. It also features an expansive four-story public lobby that will have a gourmet restaurant and sundry shop.

Working with the design architect, SOM, WSP USA provided professional mechanical, electrical, plumbing/fire protection, telecommunications and security design services for the base building. Our role on the project has continued as we are currently working on the tenant fit-out, which includes all of the office floors, as well as the lobby.

The firm also provided sustainable design services through our Built Ecology group, assisting the developer in achieving LEED® Platinum certification and exploring a wide range of innovative high performance solutions to deliver a carbon neutral building.
